One with a good synergy with his own.

His parents looked more happy to see that their children got their powers than shocked by K-T's current predicament. With the smoke dissipating K-T looked on the side to see what Emily got from the power lottery.

She had not transformed in a radical way like he did nor lost her clothes. The only change visible was that her brown hair had grown a bit and turned glossy black with a neon pink shine.

"Sweetie, what power did you get?" asked his mom to Emily, the type of power that he got being quite obvious.

"Well, let me check. I can feel I can do things but not exactly what," replied Emily. His mother was holding another tech gizmo, probably to identify their powers.

The pink glow on his sister intensified and K-T began feeling weird things. His whole body suddenly felt ticklish and very sensitive. He also felt his stomach churn and suddenly he erupted, letting go of the most powerful, nearly deafening fart that he had ever witnessed. It lasted for what seemed like forever and he was really embarrassed, unable to do anything to stop it, his sister bursting out of laughter.

"Ohh you're a metabolist, congratulations Emily. It's a very versatile power that can manipulate bodily functions, it can become very powerful once you master it." said their mom, focused on the readings of her gadgets.

"Emily, this can be a good training exercise. See if you can help your brother with his problem." said their dad, pointing at the elephant trunk in the room that was K-T's super powered boner.

Emily glowed brighter and K-T could feel some strange pressure in his cock, it was really strange since nothing was touching it.
As fast as it started the feeling ended, the glow on his sister dulled at the same time.

"I can't do it, there's something blocking me. It's probably his powers keeping himself hard." She said.

"Don't give up sweetie, not all powers are about application of brute ****. Focus, think about it and try to find a way around the blockage, I'm sure you can do it." said their mom, encouraging her to try again.

Emily glowed again and this time K-T didn't feel a pressure but a tingling. I was going from the tip of his cock to his balls and back again. As it went on K-T felt himself getting warmer and hornier, until…

With little notice, he exploded shooting what looked like a tennis ball sized clump of glowing orange cum that impacted with a tree, cracking the wood.

As soon as it happened, K-T cock softened and he began to shrink, soon being back to his original size and color. And still completely naked in front of his family, his cock now at least back to a size reasonable enough for him to hide it.

"Oh, I see. It might be a problem dear," said his dad to his mom.

"Emily it's really good that you two got powers that work together. If you are on an intervention together you'll have to do everything you can to stop your brother from finishing otherwise his life could be in danger if he loses his powers suddenly." explained his mom.

"Don't worry about missing on the action either. With powers like that it's very common to be able to impart effects that last in time or even become permanent without you having to focus on it. What worries me a bit is K-T having his powers triggered by accident." added his dad.

"You're right, he could hurt someone. K-T, we have to know what the threshold is for you to transform. First try to transform yourself by only focusing on your power." instructed his mother.

K-T tried to do what he was told. He closed his eyes and focused on strength and power. He could feel it inside it, but he didn't manage to trigger it. All he could achieve by poking at this power inside of him was to make his dick twitch and start to stiffen again.

"I can't do it, I might have to train more to be able to trigger it by myself," he explained.

"Don't worry K-T, I was afraid it would be the case. I think that your powers are linked to the state of your little friend. Could you try to make it raise to see if it works. We have to be sure, it could be dangerous if you trigger your powers every time you get a little excited." said his mother.

"Wait… you want me to… I mean in front of you all…" stuttered K-T."

"K-T, we are gathering scientific data about your powers, it could save lives one day. No one here enjoys having to see this, but it's not really like it will be the first time one of us see you masturbate. Stop being a child!"

Get hard and in the mood with no extra stimulation and in front of his family wasn't an easy task. K-T tried to stoke his slowly stiffening shaft while thinking about girls he liked. He had to ignore the snickering of his sister while doing it.

As soon as he got fully hard he felt his body shift in his Hunk form, his cock now turned into an unbending rod of massive proportions.

"This is what I feared. Let's go home, we'll go to the league's headquarters tomorrow to have you get registered as heroes and we will try to find a solution to this problem once there. Emily, turn him back again, we can't go home like that." said his dad.

Emily was glad to obey and a huge glow load cracked another tree trunk. K-T now back to his normal self would have appreciated if it had happened once they reached the car rather than now, the long walk back to it would be rather inconvenient, naked, barefoot and without super strength.

But in the end with sore feet he reached the car and had to endure yet another ride home naked in the car. The t-shirt he had removed because of the heat while exercising having mysteriously disappeared.
